LOOM HARNESS Filed March 13, 1962 INVENTORS ALBERT J. K/E/VV BY CHARLESE KRAMER ATTORNEY United States Patent 3,170,491 LOOM HARNESS Albert J.Kieny and Charles F. Kramer, Philadelphia, Pa., assignors to SteelHeddle Manufacturing Company, Philadelphia, Pa, a corporation ofPennsylvania Filed Mar. 13, 1962, Ser. No. 179,297 7 Claims. (Cl.139-82) This invention relates to loom harness for weaving and moreparticularly to apparatus for preventing the sidewise displacement ofone heddle frame with respect to the others in a weaving loom.

It is the principal object of the present invention to provide simplebut effective structure associated directly with the heddle frames forpreventing sidewise displacement of one or more of a plurality of heddlefrarnes with respect to the others.

It is a further object of the present invention to provide simple buteffective structure on loom heddle frames so that the frames are allurged into edge aligned relation.

It is a further object of the present invention to provide aligningstructure on loom heddle frames which urges the frames into alignedrelation, and which, in a preferred embodiment, may be applied to heddleframes at the time of their initial construction or subsequently addedthereto if desired.

Other objects and advantageous features of the invention will beapparent from the description and claims.

The nature and characteristic features of the invention will be morereadily understood from the following description, taken in connectionwith the accompanying drawings forming part thereof, in which:

FIGURE 1 is a front elevational view of a loom heddle frame inaccordance with the present invention;

FIG. 2 is a fragmentary prespective view of a plurality of heddle framesin accordance with the invention;

FIG. 3 is a horizontal sectional view, enlarged, taken approximately onthe line 3-3 of FIG. 1; and

FIG. 4 is a vertical sectional view, further enlarged, takenapproximately on the line 4-4 of FIG. 3.

It should, of course, be understood that the description and drawingsherein are illustrative merely, and that various modifications andchanges can be made in the structure disclosed without departing fromthe spirit of the invention.

Like numerals refer to like parts throughout the several views.

Referring now more particularly to the drawings, a plurality of heddleframes of well-known type are shown, having top and bottom rails 11 and12 and side ,r truts 13. Spaced respectively below and above the rails11 and 12, heddle supporting rods 14 and 15 are shown for supporting aplurality of heddles 16 in a well-known manner. The heddles 16 are shownas having central warp eyes 17.

The heddle supporting rods 14 and 15 can be mounted in the heddle frames10 in any desired manner with intermediate supports (not shown), and ifdesired can be restrained and held at their ends by resilient lockingclips 18 carried by the side struts 13 with locking tongues 19 engagingin locking openings 20 in the rods 14 and 15. The structure justdescribed is well known in the art and is shown merely for purposes ofexplanation of the present invention.

In order to overcome any tendency of one heddle frame 10 to becomedisplaced sidewise or horizontally, the contiguous frames 10 areprovided with members having interengaging vertically extending faceportions hereinafter described, disposed out of thernain plane of theheddle frame 10, to urge any frame 10 tending to move sidewise back to aside edge aligned position.

For this purpose, each of the heddle frames 10, on the outer faceportion 21 of the side struts I3, is provided with a plurality ofvertically spaced recesses 22 for the reception of securing portions 23of restraining brackets or plates 24. The portions 23 are held inengagement and secured to the side struts 13 in any desired manner, suchas by rivets 25 which can also serve to carry the locking clips 18.

The plates 24 have inwardly disposed face portions 26 which, by theirengagement with outer side face portions 21 of contiguous side struts 13on opposite sides, prevent appreciable separate sidewise movement of anyof the heddle frames 10. The motion restraining face portions 21 and 26are disposed in non-parallel and intersecting relation to the mainplanes of the heddle frames 10 and the heddle rods 14 and 15.

We claim:

1. In a loom having a plurality of contiguous heddle frames, means forreducing sidewise movement of any of the frames comprising members oneach of said heddle frames and vertically moved therewith having avertical face portion in interengaging relation to a vertical faceportion of a contiguous heddle frame.

2. A loom as defined in claim 1, in which the heddle frames have sidestruts and the interengaging face portions are on contiguous sidestruts.

3. A loom as defined in claim 1, in which the heddle frames havevertical side struts, and one of the face portions is a face of a sidestrut.

4. A loom as defined in claim 1, in which the heddle frames havevertical side struts and one of the face portions is on a bracketcarried by one of the side struts.

5. A loom as defined in claim 1, in which the heddle frames havevertical side struts, and said means is provided on contiguous sidestruts on both sides of said frames.

6. In a loom having a plurality of contiguous heddle frames, each of theframes at each side having members carried thereon with vertical faceportions in planes in intersecting relation to the main plane of itsheddle frame, said members on contiguous heddle frames having theirvertical face portions disposed in meeting relation and preventingsidewise displacement of each heddle frame.

7. A loom as defined in claim 6 in which each heddle frame has sidestruts with certain of said vertical face portions thereon and platescarried thereon with others of said vertical face portions on saidplates.
